How This Works
The 3D Moon is rendered using WebGL with real NASA moon surface textures. The directional light is positioned to match today's actual sun angle relative to the Moon, accurately simulating the current First Quarter phase. Drag to explore any part of the lunar surface — craters, mare basalt plains, and the lunar highlands.
